Giant
wasps nearly always form nests, though not like their much smaller
cousins. Each nest functions with one leader (the queen), a few
workers, and several soldiers. The workers and the queen produce
offspring while the soldiers protect the nest and hunt for food. Giant
wasp nests are typically found in caves, abandoned houses, or any
complex large enough to fit a dozen 10-foot-tall insects.

Giant
wasps attack when hungry or threatened, stinging their prey to death.
They take dead or incapacitated opponents back to their lairs as food
for their unhatched young—the experience of lying in a wasp nest,
paralyzed while its grubs feed, is one of nature's cruelest inventions.
Even when part of a nest, giant wasps tend toward solitary hunting, and
it's rare to see more than one at a time.
